Everyone knows that the maintenance of dump semi-trailers is especially important, from vehicle overhaul to car wash and beauty. Especially in the summer, when the air humidity is high, coupled with the frequent exposure to the sun, the number of vehicle inspections and car washes should be more frequent. 1. Inspection and replacement of lubricating oil for the dump semi trailer The inspection and replacement of lubricating oil is a necessary work for the dump semi trailer to spend the summer safely. Because excellent lubricating oil products can not only save fuel, but also reduce friction, ensure the smooth operation of the engine, and extend the service life of the dump semi-trailer. After a period of use, the performance of the lubricating oil will decrease or completely fail, and it will not continue to protect the engine. Especially the high temperature in summer can easily make the lubricating oil become thinner, leading to the deterioration of the anti-oxidant performance of the lubricating oil. This is not conducive to protecting the engine of the dump trailer, and may cause failures such as bush burning and axle suspension. 2. The lubricants of different brands of the dump semi trailer should not be confused Different brands of dumper semi-trailer lubricants generally cannot be mixed because the chemical composition of additives used by different manufacturers is different. If they are mixed, it may cause chemical precipitation between the additives. If you change the brand, you need to wash the remaining lubricating oil in the engine and replace it with new lubricating oil.
